Environmental Impact of Steel
The making of steel from the mined iron ore is also highly energy demanding. Production of steel is the most energyconsuming and CO2 emitting industrial activity in the world. Steel requires about 20 gigajoules of energy per ton produced. Three quarters of the energy comes from burning coal. Steel production is highly polluting
